TMCL: Interrupt Input Change
TMCL is the simple way to implement your motion control application. With this series of simple coding examples we want to provide you an easy start.
This programs demonstrates how to the interupt on an input change. The behaviour of this program is the same as EX0008. Depending on the status of Port IN_0 is motor 0 turning right (IN_0 = 0) or turning left (IN_0 = 1).
Before use: Restore Factory Defaults
// *** Values that have to be adapted *** // amax = 1000 //max. acceleration (0 ... 2047) vmax = 2000 //max. speed (0 ... 2047) cmax = 100 //max. current (0 ... 255) // *** Initialization / Set up axis parameter *** // SAP 5, 0, amax //set max. acceleration SAP 6, 0, cmax //set max. current // *** Interrupt initialization *** // VECT 39, changeRotation //define the interrupt vector for input change 0 interrupt (IN_0) SGP 39, 3, 3 //configure interrupt to trigger on both edge of input 0 (0=off,1=low-high,2=high-low,3=both) EI 39 //enable input change 0 interrupt (IN_0) EI 255 //globally switch on interrupt processing // *** Main Loop *** // loop: //infinite loop JA loop //jump to loop changeRotation: GIO 0, 0 //read IN_0 COMP 0 //compare with 0 JC EQ, turnRight //if equal jump to turn right ROL 0, vmax //if not equal turn left at vmax RETI //end of interrupt turnRight: ROR 0, vmax //turn right at vmax RETI //end of interrupt

This sample is tested with TMCM-1140, TMCM-1161, TMCM-6110.
